The AD suburban/panel used the EXACT same frame as the pickup so it fits the S10 EXACTLY the same way. There are a couple of outrigger body mount brackets that are on the sub/panel frame but they neither raise or lower the body. The floor of the pickup bed clears the top of the frame the same as the burb floor. Go to the
www.ad-engineering.com site and click on "customer rides". There are several suburban/panels setting on S10 frames and require no floor alteration. Pictures of a 52 Burb in shop with NO flood mods:
